"An Investigative Analysis of the Protection Performance of Unbalanced " by Muhammad Yousaf, Kashem M. Muttaqi et al.

Despite the substantial reliability and power quality improvements, the proliferation of distributed energy resources (DERs) can introduce many protection complexities in distribution networks. This research article presents a comprehensive investigative analysis of the distributed generation (DG) impacts on the protection performance of the distribution network. Various protection coordination case studies have been analyzed under different operating conditions by varying the DG penetration level or the fault conditions to highlight the potential risks of the protection networks. The severity of the risks is evaluated by considering the DG locations, protection settings, and fault types/impedance parameters on a standardized IEEE 13 node test feeder. The subsequent protection hazards are examined for the mutual coordination of the overcurrent (OC) relays, auto-reclosers, and series fuses in distribution networks along with the differential protection issues for DC bus system.

"Distance Protection of Transmission Lines in Presence of Inverter-base" by Amin Jalilian, Kashem M. Muttaqi et al.

Although it is commonly assumed that power swing is symmetrical and will have identical effects on all three-phase voltages and currents, there is another type of power swing, which is asymmetrical and mainly occurs during single-pole tripping (SPT), the impact of which on power systems integrated with the inverter-based resources (IBRs) has not been investigated so far. Since the likelihood of the occurrence of asymmetrical power swing is increasing in todays heavily loaded transmission lines, this paper investigates the impact of IBR integration on the performance of distance protection during single-pole tripping. Furthermore, a new scheme is proposed to detect earth faults that occur during asymmetrical power swings to enhance the performance of power swing blocking (PSB) functions. To do so, the superimposed component of the zero-sequence current during SPT is extracted. Then, the moving average window is used to calculate the average of both zero-sequence current and its superimp ....

"A Saturated Amorphous Alloy Core-based Inrush Current Limiter to Elimi" by Md Minarul Islam, Kashem M. Muttaqi et al.

In this paper, a new saturated amorphous alloy core-based inrush current limiter (ICL) has been designed and built to limit the inrush current of a power transformer. A toroidal core with a middle limb is developed using the Metglas amorphous alloy and the middle limb is excited with a dc current to saturate the amorphous alloy core. Only a very small dc excitation current is required using such a core when compared to that using a similar design with conventional materials. Under normal conditions, the saturated amorphous alloy ICL core steady-state impedance is low and has a negligible effect on the operation of the system. During the energization of a power transformer connected to the ICL, the large inrush current de-saturates the amorphous alloy core, resulting in an increase in the ac winding impedance, which limits the peak amplitude of the transformer inrush current and harmonics. To validate the proposed saturated amorphous alloy core-based ICL, a prototype ICL has been built ....

FOXNEWS America Reports With John Roberts Sandra Smith October 11, 2021 17:33:00

We don t know how many will make it here but they do seem to be determined so the department of homeland security will do as we look at the miles and miles of border wall fencing sitting there being stored, which will eventually rust away or be destroyed or something. dhs is saying, chad, it will take the money that was appropriated for border wall construction and put it toward environmental projects in the border region including biological cultural, and natural resource surveys. is that a productive way to spend the money, or we have some money and we have to spend it? well, it is not productive at all. not when you are talking about border enforcement and trying to bring rule of law to the border. you need to provide the resources to the men and women who are down there every day doing this job. time and time again, they have been pleading with multiple administrations building an effective border wall system. why? it gives them impedance and denial of the technology they need al ....

Them where individuals are crossing the border when they don t have the resources or the they can t respond to them. again, they need impedance and denial, meaning an individual crossing the border wanting to cross the border is slowed down and is somehow stopped until they can get there and apprehend the individual. there is a multitude of ways to bring security and bring operational control back to the border but it starts with effective border wall system. you can lay on top of that the different technologies that you need to. john: as we saw a couple of weeks ago the only way to stop the migrants to walk across the dam in del rio, texas dps lined up the cars and basically made a wall out of cars. chatted with them always good to see you, thank you for joining us today come appreciate it. sandra? sandra: gabby petito fugitive brian laundrie by fox news and entertained this exclusive video of his parents emerging from florida home under the cover of darkness to remove various thi ....
